Phygelius plant named &#39;Yapcor&#39;

ABSTRACT

A new cultivar of  Phygelius  named ‘YAPCOR’ that is characterized by a compact well-branched habit, burgundy stems and deep coral-pink pendulous flowers. In combination these traits set ‘YAPCOR’ apart from all other existing varieties of  Phygelius  known to the inventor.

PHYGELIUS PLANT NAMED ‘YAPCOR’

Genus: Phygelius Species: aequalis x rectus Denomination: ‘YAPCOR’

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Phygelius, that is grown for its ornamental pendulous red flowers and burgundy stems. The new cultivar is known botanically as Phygelius aequalis×rectus and will be referred to hereinafter by the cultivar name ‘YAPCOR’.

The inventor has been interested for some fifteen years in the genus Phygelius, and has collected many named and unnamed plants of the three species of Phygelius, namely Phygelius aequalis, Phygelius capensis, and the inter-specific Phygelius×rectus (P. aequalis×capensis). The inventor has recognized that the genus would be more widely produced and sold commercially if its growth habit would be shorter and more sturdy with natural self-branching. The species of Phygelius and most of the available cultivars, exhibit a vigorous upright growth, such that, although the flowers are much admired, the habit of the plant itself is unappealing to some gardeners. Although it is possible to induce branching and shorter intemodes by the application of plant growth regulators during the production cycle, the effect of such applications wears off as the season proceeds and the plants fail to remain upright without staking or support from adjacent plants.

‘YAPCOR’ was bred by the inventor in a cultivated area of Cheshire, England. ‘YAPCOR’ is one of three varieties selected for release from the same breeding program. The companion varieties ‘YAPOR’ and ‘YAPYEL’ are the subject of contemporaneous applications. The plant habits of YAPCOR’, ‘YAPOR’ and ‘YAPYEL’ are similarly compact, and their flower colors are respectively dark coral pink, orange and yellow. ‘YAPCOR’ arose as follows:

In 1990, the inventor purchased a single plant of Phygelius labeled simply as Phygelius aequalis, that is, without a cultivar designation. This plant carried the characteristic pale yellow flowers of the species Phygelius aequalis but the inventor was attracted by its uncharacteristic compact habit. The inventor allowed the plant to run to seed, then harvested a quantity of seed which was sown and grown out as a seedling population. The inventor selected a single plant from this population and named it “Compact Primrose”. Compact Primrose was retained by the inventor as a useful parent for a future breeding program aimed at producing a series of complementary flower colors on plants with natural compactness and good branching. Compact Primrose grows to a height of 40 cm in the season whereas plants of the genus typically achieve heights of or exceeding 70 cm in one growing season. Compact Primrose, which has never been made available to the public, has been maintained and renewed by vegetative propagation at the inventor's nursery in Somerford, Cheshire, England.

In 1998, the inventor commenced his program to derive a series of compact cultivars of Phygelius. The inventor selected a single plant of Phygelius×rectus ‘African Queen’ (unpatented) for hand cross-pollination with Compact Primrose. The inventor used flowers from both plants as both pollen donors and pollen receptors and seed was collected from both plants for sowing and seedling grow-out in 1999. From plants selected in 1999 and vegetatively propagated and grown to flowering in 2000, the inventor selected ‘YAPCOR’ as presenting the best combination of improved plant habit and distinct and clear flower color and overall compatibility with the contemporaneously selected varieties ‘YAPOR’ and ‘YAPYEL’ whose breeding had followed the same procedure, namely the use of a promising parent as alternate parent with Compact Primrose as described in the relative applications ‘YAPOR’ and ‘YAPYEL’).

The distinguishing characteristics of ‘YAPCOR’ are flower color and plant habit. Whereas the one parent, Compact Primrose, exhibits pale yellow flowers without any color variation in the tube, the flowers of ‘YAPCOR’ are dark coral pink with yellow coloration of the inside of the corolla tube. Whereas the alternate parent, Phygelius×rectus ‘African Queen’ is approximately 70 cm in overall height with sparse basal branching and salmon-red flowers, ‘YAPCOR’ is approximately 40 cm in height, exhibits multiple branching and dark coral-pink flowers. The closest varieties in overall habit known to the inventor are the inventor's varieties ‘YAPOR’ and ‘YAPYEL’ which differ in flower coloration.

‘YAPCOR’ was first asexually propagated by the inventor in Cheshire, England in 1999 using softwood cuttings. Since that time, under careful observation, the distinguishing characteristics have been determined stable and uniform in successive generations.

SUMMARY OF THE INVENTION

The following represent the distinguishing characteristics of the new Phygelius cultivar ‘YAPCOR’. In combination these traits set ‘YAPCOR’ apart from all other existing varieties of Phygelius known to the inventor. ‘YAPCOR’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.

1. Phygelius ‘YAPCOR’ is 35 cm-40 cm in height and approximately as wide.

2. Phygelius ‘YAPCOR’ branches naturally from the base when grown in a container.

3. Phygelius ‘YAPCOR’ may spread by underground stolons when planted in the ground in conditions where it remains perennial.

4. Phygelius ‘YAPCOR’ exhibits pendulous clusters of dark coral pink flowers in summer and fall.

5. Phygelius ‘YAPCOR’ exhibits green leaves and burgundy stems.

6. Phygelius ‘YAPCOR’ tolerates temperatures of minus 5° Celsius to minus 8° Celsius.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrate the distinguishing traits of the new Phygelius cultivar ‘YAPCOR’. The plant photographed was in its first season of growth at the inventor's nursery in Cheshire, England. The plant was started as a cutting in early spring and potted into a 1 liter pot in a cool greenhouse (temperature maintained at or above 10 degrees Celsius) prior to being stood outside after the risk of frost.

The drawing labeled as FIG. 1 illustrates a plant of ‘YAPCOR’ at the time of removal from the greenhouse, around May. FIG. 1 depicts the basal branching habit of ‘YAPCOR’ and illustrates the burgundy flower stems with flowers still in tight bud.

The drawing labeled as FIG. 2 illustrates a close-up view of an inflorescence of ‘YAPCOR’. FIG. 2 depicts the burgundy stem color, the deep pink corolla tubes, the exserted stamens and the yellow coloration to the inside of the corolla tube.

All photographs were taken using conventional techniques and are considered reasonably representative of the foliage and flower colors of ‘YAPCOR’ although to the naked eye flower color appears to vary according to ambient light conditions.
